Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sintering machine, in particular to a sintering machine trolley end face sealing device and sintering machine trolley group. BACKGROUND

[0002] In the metallurgical industry, sintering machine air leakage has been a difficult problem in sintering production, and reducing the air leakage rate of the sintering machine is an effective measure to improve the output of sinter and save electric energy.

[0003] The sintering machine trolley runs at high temperature and generates a lot of dust. The trolley end faces contact each other, and after continuous wear and tear, the originally two contacting planes will form uneven gaps, causing air leakage. In order to reduce the air leakage rate, the existing method is to install a lining plate on the trolley end face to replace the worn trolley end face for sealing. Although this method can reduce the air leakage rate, the lining plate also has the problem of contact wear and tear, and has a short service life and must be replaced regularly. Due to the requirements of the sintering process, the sintering machine cannot be stopped at any time, so when the lining plate wears and leaks during the sintering process, there is nothing to do. Therefore, the existing method cannot well solve the problem of sintering machine air leakage. SUMMARY

[0004] The purpose of the present application is to design a sintering machine trolley end face sealing device and sintering machine trolley group to solve the problem of sintering machine trolley end face air leakage.

[0005] The present application is achieved by the following technical solutions:

[0006] The present application provides a sintering machine trolley end face sealing device, comprising a vertically extending mounting plate, a sealing block and a fixed plate; the mounting plate and the fixed plate are arranged opposite in the transverse direction and form an air leakage zone therebetween; the surface of the fixed plate facing the mounting plate is provided with a vertically extending insertion slot; the sealing block is arranged between the mounting plate and the fixed plate; the first end of the sealing block is rotatably connected to the mounting plate, and the second end of the sealing block extends into the insertion slot in the transverse direction; the rotation axis of the sealing block is vertically arranged, and when the sealing block rotates around its rotation axis, the second end of the sealing block can swing in the insertion slot and can abut against the slot wall of the insertion slot in the longitudinal direction to form a contact sealing zone.

[0007] When the above setting structure is adopted, the second end of the sealing block rotatably connected to the mounting plate extends into the slot of the fixed plate oppositely arranged with the mounting plate in the transverse direction, and the second end of the sealing block can be in contact with the slot wall of the slot to form a sealing, so that when the two sides of the sealing block in the longitudinal direction have a pressure difference, the second end of the sealing block can be deflected towards the side with smaller pressure and abut against the slot wall of the corresponding side to block the air leakage belt, preventing the airflow from flowing along the longitudinal direction from the air leakage belt. Therefore, when the sintering machine trolley end face air leakage occurs, the sintering machine trolley end face sealing device can reduce the air leakage rate by using the air pressure difference to form a contact sealing belt between the sealing block and the slot wall, solving the problem of sintering machine trolley end face air leakage.

[0008] Further, in order to better achieve the present application, the following setting structure is adopted: one of the slot walls is embedded with a vertically extending high-temperature-resistant elastic sealing element, and the second end of the sealing block can abut against the elastic sealing element to form the contact sealing belt.

[0009] When the above setting structure is adopted, the elastic sealing element embedded in the slot wall has a certain elasticity, which can deform when abutting against the sealing block to provide better sealing performance, and can ensure sealing performance even under certain wear conditions. The elastic sealing element has high-temperature-resistant characteristics, which can ensure that the elastic sealing element can adapt to the high-temperature environment of the sintering machine and will not fail. Since the elastic sealing element is embedded in the slot, it can be replaced.

[0010] Further, in order to better achieve the present application, the following setting structure is adopted: the slot is arranged as a trapezoidal slot.

[0011] When the above setting structure is adopted, the slot opening is large, which can compensate for the error between the two sections of the trolley, and can guide the sealing block through the slot wall during the insertion of the sealing block into the slot, avoiding the sealing block from hitting the fixed plate, thereby playing a protective role.

[0012] Further, in order to better achieve the present application, the following setting structure is adopted: the surface of the mounting plate facing the fixed plate is provided with a vertically extending mounting slot; the bottom of the mounting slot is a circular arc bottom; the first end face of the sealing block is arranged as a circular arc surface matching the bottom of the mounting slot, and the first end of the sealing block extends into the mounting slot and is in contact with the bottom of the mounting slot.

[0013] Further, in order to better realize the present application, the following arrangement is adopted: the mounting plate comprises a plate body and a pressing plate; the mounting groove is arranged on the surface of the plate body facing the fixed plate, the bottom end of the mounting groove is closed and an opening is formed on the top of the plate body; the pressing plate is detachably fixedly connected to the top end of the plate body and covers the opening; the pressing plate is provided with an axle hole; the top end of the sealing block is provided with a rotating shaft, and the sealing block is hinged to the pressing plate through the rotating shaft.

[0014] When the above arrangement is adopted, the opening formed on the top end of the plate body can facilitate the installation and replacement of the sealing block when the pressing plate is detached.

[0015] Further, in order to better realize the present application, the following arrangement is adopted: the mounting groove is arranged as a U-shaped groove; the cross section of the sealing block is in a pear-shaped structure, and the longitudinal dimension of the first end is greater than that of the second end.

[0016] Further, when the second end of the sealing block abuts against the groove wall of the insertion groove, the sealing block has a gap with the groove wall of the mounting groove.

[0017] When the above arrangement is adopted, when the second end of the sealing block abuts against the groove wall of the insertion groove, a gap is left, so that when the second end of the sealing block and the elastic sealing member are worn, there is a compensation allowance, so that the sealing block can rotate more angles and always keep in contact with the elastic sealing member for sealing.

[0018] Further, in order to better realize the present application, the following arrangement is adopted: the mounting groove and the insertion groove are arranged opposite to each other in the transverse direction.

[0019] Further, in order to better realize the present application, the following arrangement is adopted: the opposite surfaces of the mounting plate and the fixed plate are parallel to each other.

[0020] The present application also provides a sintering machine trolley set, which comprises a plurality of trolleys and the above-mentioned sintering machine trolley end face sealing device; all the trolleys are arranged in sequence and connected; a set of the sintering machine trolley end face sealing device is arranged at the connection between each two adjacent trolleys; the mounting plate of the sintering machine trolley end face sealing device is vertically arranged and fixedly connected to the outer side surface of the guard plate of one of the two adjacent trolleys, and the fixed plate of the sintering machine trolley end face sealing device is vertically arranged and fixedly connected to the outer side surface of the guard plate of the other of the two adjacent trolleys.

[0021] When the above arrangement is adopted, the sintering machine trolley end face sealing device is arranged on the outer side of the guard plate of the trolley, without any structural change of the trolley, and is convenient to replace. The sintering machine trolley end face sealing device uses the sealing block to extend into the insertion groove to realize sealing by using pressure difference, without large wear, and has a long service life.

[0022] Further, in order to better realize the present application, the following arrangement structure is particularly adopted: the surface of the mounting plate facing the fixing plate is arranged flush with the end surface of the trolley connected thereto, and the surface of the fixing plate facing the mounting plate is arranged flush with the end surface of the trolley connected thereto.

[0023] The present application has the following advantages and beneficial effects:

[0024] In the present application, the second end of the sealing block rotatably connected to the mounting plate extends into the slot of the fixing plate arranged opposite to the mounting plate in the transverse direction, and the second end of the sealing block can be in contact with the slot wall of the slot to form a seal. Thus, when the two sides of the sealing block in the longitudinal direction have a pressure difference, the second end of the sealing block can be deflected towards the side with smaller pressure and abut against the slot wall of the corresponding side of the slot to block the air leakage zone, thereby preventing the airflow from flowing along the longitudinal direction through the air leakage zone. Therefore, when the sintering machine trolley end face sealing device is applied to the sintering machine trolley, it can reduce the air leakage rate by using the air pressure difference to form a seal between the sealing block and the slot wall when the trolley end face leaks air, thereby solving the problem of air leakage at the trolley end face of the sintering machine.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0037] Example 1:

[0038] A sintering machine trolley end face sealing device can effectively reduce the air leakage rate between the trolley end faces, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, it is particularly configured as follows:

[0039] The sintering machine trolley end face sealing device is used to be installed on the outside of the trolley's guardrail, and includes a mounting plate, a sealing block 2 and a fixing plate 3. The mounting plate, sealing block 2 and fixing plate 3 all extend vertically.

[0040] The mounting plate and the fixing plate 3 are oppositely arranged in the transverse direction, the opposite faces of the mounting plate and the fixing plate 3 are parallel to each other and vertically arranged, the mounting plate and the fixing plate 3 have a gap, and a longitudinally extending air leakage zone 7 is formed. The face of the fixing plate 3 facing the mounting plate is provided with a vertically extending slot 31. The sealing block 2 is integrally arranged at a position between the mounting plate and the fixing plate 3, the first end of the sealing block 2 in the transverse direction is rotatably and sealingly connected to the mounting plate, the rotation axis of the sealing block 2 is vertically arranged, and the second end of the sealing block 2 in the transverse direction extends into the slot 31 in the transverse direction. The longitudinal dimension of the second end of the sealing block 2 is smaller than the slot width of the slot 31, so that the second end of the sealing block 2 can swing in the slot 31. The end of the second end of the sealing block 2 has a gap with the slot bottom of the slot 31, so that the air leakage zone 7 extends towards the slot 31 at the sealing block 2, then passes through the gap between the end of the second end of the sealing block 2 and the slot bottom of the slot 31 to continue to extend after bypassing the sealing block 2.

[0041] The first end of the sealing block 2 can be connected to the face of the mounting plate facing the fixing plate 3 through a hinge, and the connection part of the sealing block 2 and the mounting plate is preferably air-tight to prevent air flow from passing through the connection part and reduce air leakage rate. The air-tightness can be achieved by sealing the gap of the connection part through smearing sealant or welding.

[0042] As a preferred connection scheme of the sealing block 2 and the fixing plate 3, in the scheme, the sealing block 2 is rotatably embedded in the mounting plate. Specifically, the face of the mounting plate facing the fixing plate 3 is provided with a vertically extending mounting slot 11, and the mounting slot 11 and the slot 31 are oppositely arranged in the transverse direction. The mounting slot 11 has a sealing plate at the bottom end and the top end, the slot bottom is provided with a semicircular arc bottom, and the whole is a semicircular arc U-shaped slot. The cross section of the sealing block 2 is in a pear shape structure, the longitudinal dimension of the first end is greater than that of the second end, and the first end face is provided with a semicircular arc surface matched with the slot bottom of the mounting slot 11. The first end of the sealing block 2 extends into the mounting slot 11 and is in contact with the slot bottom of the mounting slot 11. The top end of the sealing block 2 is provided with a rotating shaft 21, the rotating shaft of the top end of the sealing block 2 is inserted into the shaft hole of the top sealing plate and is hinged with the sealing plate, and the bottom end of the sealing block 2 is seated on the bottom sealing plate. Since the first end of the sealing block 2 is matched with the slot bottom of the mounting slot 11, the first end of the sealing block 2 has good matching with the slot bottom of the mounting slot 11, and the sealing block 2 can always maintain good air-tightness during rotation around the rotation axis.

[0043] When the sealing block 2 rotates forward around the rotation axis, the second end of the sealing block 2 can swing in the slot 31 towards one side and abut against one side of the slot wall of the slot 31 to form a contact sealing zone. When the sealing block 2 rotates reversely around the rotation axis, the second end of the sealing block 2 can swing in the slot 31 towards the other side and abut against the other side of the slot wall of the slot 31 to form a contact sealing zone.

[0044] In this embodiment, the second end of the sealing block 2 connected to the mounting plate in rotation extends into the slot 31 of the fixed plate 3 arranged opposite to the mounting plate in the transverse direction, and the second end of the sealing block 2 can be in contact with the slot wall of the slot 31 to form a seal. Thus, when there is a pressure difference between the two sides of the sealing block 2 in the longitudinal direction, the second end of the sealing block 2 can be deflected towards the side with smaller pressure and abut against the slot wall of the corresponding slot 31 to block the air leakage strip 7, thereby preventing air flow from flowing along the longitudinal direction through the air leakage strip 7. Therefore, when the sintering machine trolley end face air leakage occurs, the sintering machine trolley end face sealing device can reduce the air leakage rate by using the air pressure difference to form a contact seal between the sealing block 2 and the slot wall of the slot 31, thereby solving the problem of sintering machine trolley end face air leakage.

[0045] Embodiment 2:

[0046] This embodiment is further optimized on the basis of the above embodiments, and further better implements the present application, in particular by adopting the following setting structure:

[0047] One side of the slot wall of the fixed plate of the sintering machine trolley end face sealing device is provided with a vertically extending dovetail type embedding groove, and an elastic sealing element 4 extending in the vertical direction is embedded in the embedding groove. The elastic sealing element 4 has the characteristic of high temperature resistance. The elastic sealing element 4 has a certain elasticity, and the function of the elasticity is to provide sealing capacity. During the oscillation of the second end of the sealing block 2 in the slot 31, the elastic sealing element 4 can abut against the sealing block 2 to form a contact sealing band.

[0048] In this embodiment, the elastic sealing element 4 is provided instead of the slot wall of the slot 31 directly contacting the sealing block 2. The elastic sealing element 4 embedded on the slot wall of the slot 31 has a certain elasticity, which can deform when abutting against the sealing block 2 to provide better sealing performance, and can ensure sealing performance even in the case of certain wear. The elastic sealing element 4 has the characteristic of high temperature resistance, which can ensure that the elastic sealing element 4 can adapt to the high temperature environment of the sintering machine and will not fail. Since the elastic sealing element 4 is connected to the slot 31 in the embedded manner, it can be replaced.

[0049] Embodiment 3:

[0050] This embodiment is further optimized on the basis of any of the above embodiments, and further better implements the present application, in particular by adopting the following setting structure:

[0051] In this embodiment, the slot 31 of the sintering machine trolley end face sealing device is provided as a trapezoidal slot, and the longitudinal dimension of the slot opening is greater than the longitudinal dimension of the slot bottom.

[0052] In this embodiment, the trapezoidal groove has a larger notch, which can compensate for the error between the two trolleys. The groove wall is a slope, which can guide the sealing block 2 through the groove wall during the insertion of the sealing block 2 into the slot 31, thereby preventing the sealing block 2 from hitting the fixed plate 3, playing a protective role, and ensuring that the sealing block 2 and the fixed plate 3 have a longer service life.

[0053] Example 4:

[0054] This embodiment is a further optimization based on any of the above embodiments. To better implement the present invention, the following configuration is particularly adopted:

[0055] In this embodiment, the mounting plate of the sintering machine trolley end face sealing device is configured as a split structure, which includes a detachably connected plate body 1 and a pressing plate 5 .

[0056] Specifically, the mounting groove 11 is provided on the surface of the plate body 1 facing the fixed plate 3 , and a sealing plate is provided at the bottom end of the mounting groove 11 to seal the bottom end of the mounting groove 11 . The mounting groove 11 forms an opening 12 at the top of the plate body 1 .

[0057] The pressure plate 5 is detachably fixed to the top of the plate body 1 by bolts, and the pressure plate 5 serves as a sealing plate at the top of the mounting groove 11 to cover the opening 12. The pressure plate 5 has a vertically extending shaft hole, and the rotating shaft set at the top of the sealing block 2 is inserted upward into the shaft hole to achieve hinged connection.

[0058] In this embodiment, the top of the plate body 1 is formed with an opening 12, which allows the sealing block 2 to be conveniently installed into the installation groove 11 from the top or side when removing the pressure plate 5. After installing the sealing block 2, only the pressure plate 5 needs to be covered. The split design is not only convenient for installing the sealing block 2, but also for replacing it.

[0059] Example 5:

[0060] This embodiment is a further optimization based on any of the above embodiments. To better implement the present invention, the following configuration is particularly adopted:

[0061] In this embodiment, the sintering machine trolley end face sealing device reserves a rotation margin for the sealing block 2. Specifically, when the second end of the sealing block 2 abuts the groove wall of the slot 31, a gap is left between the sealing block 2 and the groove wall of the mounting slot 11. This gap, when the second end of the sealing block 2 abuts the groove wall of the slot 31, allows for a compensation margin to compensate for wear between the second end of the sealing block 2 and the elastic seal 4, allowing the sealing block 2 to rotate to a greater angle, ensuring that the sealing block 2 always maintains contact and sealing with the groove wall of the slot 31 or the elastic seal 4.

[0062] Example 6:

[0063] The embodiment is further provided on the basis of any of the above embodiments, and particularly adopts the following arrangement structure:

[0064] The sintering machine trolley set comprises multiple trolleys 6 and sintering machine trolley end face sealing devices. All the trolleys 6 are arranged in sequence and connected to form a trolley set. Each of the end face connecting portions between the adjacent two trolleys 6 is provided with a set of sintering machine trolley end face sealing devices.

[0065] Specifically, the mounting plate in the embodiment 4 is taken as an example for illustration. The sintering machine trolley end face sealing device is vertically arranged and mounted on the outer side of the guard plate of the trolley 6. Specifically, one side of the plate body 1 in the longitudinal direction is fixedly connected to the outer side of the guard plate of one of the adjacent two trolleys 6, and one side of the fixed plate 3 in the longitudinal direction is fixedly connected to the outer side of the guard plate of the other of the adjacent two trolleys 6. The surface of the plate body 1 facing the fixed plate 3 is arranged in flush with the end face of the trolley 6 connected thereto, and the surface of the fixed plate 3 facing the mounting plate is arranged in flush with the end face of the trolley 6 connected thereto.

[0066] When the two trolleys are end to end and abut against each other, the sealing block 2 in the sintering machine trolley end face sealing device extends into the insertion groove 31 and leaves a gap with the groove bottom of the insertion groove 31.

[0067] In the embodiment, the sintering machine trolley end face sealing device is arranged on the outer side of the guard plate of the trolley 6, without any structural change of the trolley 6 and convenient replacement. The sintering machine trolley end face sealing device uses the sealing block 2 extending into the insertion groove 31 to achieve sealing by using pressure difference, without large wear and with long service life.

[0068] The sintering machine trolley end face sealing requires strictness, which requires that the trolley maintains a sealed state during walking, and when the trolley enters the tail bend of the sintering machine, the sealing device is not abraded when the end portion of the trolley is fan-shapedly opened, and the sealing device is not extruded and damaged when the trolley automatically forms a sealed environment when it is about to walk out of the bend. The sintering machine trolley end face sealing device adopted by the sintering machine trolley set of the present application uses the form of pressure difference blocking air leakage belt to achieve the sealing effect, with low wear rate and meeting the strict requirements of the sintering machine trolley end face sealing.

[0069] In the process of sintering machine trolley operation, when the trolley 6 walks to the sintering area, the end face of the two trolleys 6 is not completely closed, resulting in negative pressure formed by air leakage. The pressure difference will drive the sealing block 2 to rotate and automatically adsorb to the high-temperature-resistant elastic sealing element 4, and through the abutment and fitting with the elastic sealing element 4, a contact sealing band is formed to block the air leakage belt 7. When the trolley 6 walks out of the sintering area and is about to enter the tail curve, the sealing block 2 and the elastic sealing element 4 are separated with the separation of the two trolleys. When the trolley 6 enters the sintering area again, the two trolleys 6 are close, the mounting plate and the fixed plate 3 are close slowly, and the sealing block 2 can be automatically inserted into the slot 31 under the guidance of the slot wall of the slot 31 of the fixed plate 3. When the two trolleys 6 are completely close together, the sealing block 2 is completely inserted into the slot 31, and under the condition of negative pressure, the sealing block 2 is again automatically fitted with the elastic sealing element 4. Thus, the technical problem of air leakage at the end of the sintering trolley is solved.

[0070] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
